Measure the ice cream into a bowl. You can let it melt at room temperature for 20 to 30 minutes, or microwave it in 20-second intervals, stirring occasionally, until it's mostly melted (you don't want hot liquid). I like to use the defrost button, which reduces the microwave power in half.
Add the self-rising flour and cocoa powder to a large bowl, and mix it well. Pour the melted ice cream and vanilla extract into the bowl. Stir until it's mostly smooth. The batter is a little lumpy.
Cook the pancakes:
Heat a non-stick pan or griddle over medium heat. Once hot, grease it, and immediately pour ¼ cup of batter per pancake. Cook the first side for about 2 minutes, flip the pancakes over, and cook the second side for a little less time. If your pancakes are browning too fast and you're flipping them over before bubbles have formed throughout, reduce the heat and rinse the pan between batches.
Serve & store:
Serve these hot, topped with butter and syrup, chocolate syrup and whipped cream, or go to town and add a scoop of ice cream on top.
Leftover pancakes can be stored in an airtight container in the fridge for up to 4 days.
Notes
Using pancake mix: Measure 1 ¼ cups of pancake mix. Since it already has baking powder, it can be used.
Using all-purpose flour: Combine 1 ¼ cups of flour with 2 ½ teaspoons of baking powder in the bowl.
Using vegan ice cream: I tested this using a vegan ice cream, and while the pancakes turned out, they were a bit denser. This is because traditional ice cream is made with eggs and milk, two ingredients found in traditional pancake batter.
Making these non-chocolate: omit the cocoa powder, reduce the ice cream amount to 1 ¼ cups (same as the flour).
